  • Method, furnace shell, and furnace for rebaking and graphitizing carbon bodies
    Patent number: 6834072
    Abstract: A method rebakes and graphitizes pitch-impregnated carbon bodies in an encapsulated Castner-type lengthwise graphitization furnace in one step. A furnace shell is constructed of element modules and can carry out the method. A furnace utilizes the furnace shell. The oxygen content in the interior of the furnace is kept below 4% by volume. The method is carried out under atmospheric pressure or at pressures that differ only slightly from the atmospheric pressure.
